1800-1920 middle is 1860. I think currently SPX is building this middle line in advance.
So down to 1800 would be the first step in the near future, then rally to 1920.
SPX has risk to its MA50. So I dumped my long positions.
Now I wonder if 1800-2000 channel would be the case...40 point lower than I previously thought...This implies that SPX would bottom at 1800, then 1920.
Between Monday and Tuesday, there was a 20 points gap(1845-1865).
So far market gives no intention to fill it.
I guess that after "1940-1950做顶", the gap will be filled when "回来再次考验1840".
